Dual-phase cohesive zone modelling and experimental validation for hydrogen-assisted cracking of 2205 duplex stainless steel
(Elsevier, 2021-01-01)
The hydrogen-assisted cracking (HAC) behavior of 2205 duplex stainless steel is investigated via experimental testing and computational modelling, with specific focus on developing a predictive methodology for the coupled ...
A physically-based method for predicting high temperature fatigue crack initiation in P91 welded steel
(Elsevier, 2021-08-27)
A methodology is presented for physically-based prediction of high temperature fatigue crack initiation in 9Cr steels, with a focus on material inhomogeneity due to welding-induced metallurgical transformations. A modified ...
A dislocation-based yield strength determination model in nano-indentation test
(SAGE Publications, 2021-02-20)
This paper presents a dislocation-based yield strength model for the nano-indentation size effect. The model is based on functional expressions involving the densities of statistically stored dislocations and geometrically ...
Welding-induced yield strength heterogeneity in X100Q: Modelling and characterisation
(Elsevier, 2021-09-14)
Yield strength (YS) heterogeneity in X100Q high strength low alloy (HSLA) steel welded joints is a key factor which influences fatigue life performance. The effects of welding-induced microstructural changes are investigated ...
